Question

What is difference between emf and voltage

Answer 1

Dear student, 1. EMF is the maximum potential difference between the two electrodes of a cell when the cell is in the open circuit Whereas, the potential difference between the two points is the difference of potential between any two points in a closed circuit. 2. We can measure potential difference or voltage between any two points, but EMF exists only between the two electrodes of a source. Regards
